Yes, it is good news, because it's the very start of them starting to acknowledge that actually female people do have some rights, and it's not just males who have rights dependent on their special feels.
Once you confront the fact that rapists should not be allowed into women's prisons there's really no turning back, because you've conceded that the women in the prison are entitled to rights, and that means that any male in the population is revealed as unacceptable.
Men should not be allowed into women's prisons. Ever. Not with a special certificate, or special feelings, or long hair, or lipstick. Not if they are lovely, or a right laugh, or very sad.
Not if you concede that the women in prison also have rights.
